' Letters Patent No. 64,317, dated April 30, 1867.

GATE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WINDSOR HOLDBEDGE, of Oxford, in the county of Chonango, and Stateof New York, have invented an improved Gate for farm and other purposes; .and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this Figure 1, being a top view of said gate; and

Figure 2 a section in the line a: offig. 1. i

The same letters refer to corresponding parts in each of the drawings.

My improved gate is constructed of slatsp q, united with each other by central and end pivots on what is known as the lazy-tongs principle. 7 Thesustaining, guiding, and protecting framework of my said improved gate is composed of the following parts, viz:

Parallel beams A A; transverse connecting timbers B (1; the side gate-post 1),, rising from its connection with the transverse timber B; the side gate box, composed of upright casings F F, which rise from their connection with the transverse timber C, and which are connected at their upper ends by the cover G, and at their outer edges by the vertical casing H, all as represented in the drawings, or substantially the same. A thick plank, E, is placed upon and firmly secured to the transverse timber C, and to the inner edge of this plank the two operating platforms J J, which extend across the roadway, are hinged. Suitable ways, for guiding and supporting the slattedgate, arelocated between the inner'edges of the platforms JJ. The said hinged piatforms J J are connected with the gate (1 in such a manner that the depression of the vibrating ends of either platform will depress the other, and suchdeprcssion will so act upon the gate as to condense it to its smallest coinpass within the side box F G H, and thereby open the roadway between said box and the gate-post D. The elevation of the vibrating ends of the said platforms J J, by means of either springs or weights, will instantly expand the gate across the roadway, and force its outer slats, p q, firmly against the gate-post D, as represented in the drawings. Motion is communicated from the platforms J J directly to the'cxtreme inner gate-slatp, in the manner represented infig. 2, vizythc transverse shaft in, whose pivots work in apertures in the side beams A A, is connected to the platforms J J by means of its horizontally projecting levers Z Z, that are jointed to short arms is k, which descend from the vibrating ends of said platforms, whilst the lever 12, which descends vertically from said shaft, is jointed to one end of the long crooked lever y, whose opposite end is jointed to the innermost slat pof the gate. It will, therefore, be readily perceived that the thrust of the lever y will condense the gate by carrying its componentjointed slats into a nearly vertical position, and that a drawing action exerted upon said lever will produce an expansive action upon said gate by bringing its slats into an inclined position. The platforms J J may be kept at their extreme point of elevation, and the gate thereby kept in the expanded position represented'in thedrawings, by means of strong springs, t t, placed between the said platforms and the transverse timber B; or the said platforms may be kept in an elevated position by means of cords v, and a weight, 10, substantially as represented in the drawings. The weight or springs must be so graduated in their action upon the platforms J 'J that the stopping of the forward feet of a horse or an ox thereupon will depress the platforms, and thereby throw the gate into its side receiving box, and retain it there until the weight has been removed from the platforms by the passage over the same of the horses or oxen and whatever vehicle may be attached to them. 7 i

What I claim as my invention, and desire to seeuro by Letters Patent, is

Connecting the expansi-ble and contractiblc gate 2) q with the hinged platforms J J, by means of the descending arms k 7:, the horizontal levers ZZ,-tho horizontal shaft 111, the vertical arm n, and the crooke-l lover y, in such a manner that the depression and elevation of either of said platforms will operate said gate, substantially in the manner herein set forth. V

Thc aforegoing specification of my improved gate for farm and other purposes, signed and witnessed this 22d day of February, 18(ii'. I
